SNOW-MELTING APPARATUS.

Application filed July 27, 1914.

T 0 all wlz om it may concern:

Be it known that I, SOLOMON DENEMARK, a citizen of the United States,and residing at Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Snow- MeltingApparatus, of which the following is a specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to snow melting apparatus, and the object thereofis to provide an apparatus of this class mounted on or made in the formof a truck and which can be easily moved about from place to place andwhich is simple in construction and effective in operation and which maybe used wherever apparatus of this class is desired.

The invention is fully disclosed in the following specification of whichthe accompanying drawings form a part, in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe views, and in which Figure 1 is a sectional side view of my improvedsnow melting apparatus ;Fig. 2 a section on the line 22 of Fig. 1;-Fig.3 a vertical transverse section on the line 3-3 of Fig. 1;Fig. 4; avertical section on the line 44 of Fig. 1; Fig. 5 a perspective view ofa pump operating lever which I employ ;Fig. 6 a plan view of one of thegasolene tanks which I employ and showing burner supply pipes connectedtherewith, and ;Fig. 7 a view similar to Fig. 1, but showing only adetail of construction and showing the same on an enlarged scale.

In the drawing forming part of this specification, I have shown atruck'frame a having front wheels (1 and rear wheels (1 and a front seata, and in carrying my invention into effect, I mount on the truck framea body I) which may be composed of any suitable material, and which isoblong and approximately rectangular in form, and which comprises sidewalls 6 a front end wall 6 and a rear end wall I)", and the side walls 6are provided with doors I), and mounted over the body I) is a hopper c.

Placed longitudinally in the bottom of the body 2) and in the oppositesides thereof are gasolene tanks d, and in the body I) and above thetank (Z and flush with the inner walls of said tank are verticalpartitions b Specification of Letters Patent.

Patented Nov. 24., 1914.

Serial No. 853,317.

forming a central longitudinal snow chamber 6 the bottom of whichconsists of a wall b of the body is provided with an opening 6 and thetrough is provided with a backwardly directed extension d having adischarge spout d adapted to discharge snow water into a trough (Zf bywhich it may be conveyed to a sewer or drain and the discharge spout clmay be provided with a flexible hose (Z for conveying the snow water tothe trough d.

Placed in the extension 612 of the trough b is a valve door d hinged at(P, and with which is connected at d a chain or other flexible device d"which passes over a pulley al at the top of the body, and by means ofwhich the door (1 may be raised or opened when desired, and above thetrough b the rear end of the body is also provided with a door 6 whichmay also be raised for the purpose of discharging stones or otherforeign substances that may be s'hoveled into the body with the snow,and which will collect on the perforated cover I) of the trough 6 Ateach side of the body and above the gasolene tanks d are placed two leadpipes 7, said pipes being in the same horizontal plane and each pair ofsaid pipes is connected with the bottom of the corresponding tank (Z atthe front of the body by vertically arranged pipes f and the lead pipesand vertically arranged pipes f are provided at the front end of thepipes f with needle valves P.

The stand pipes f connected with the inner lead pipes f of each pair areshorter than the stand pipes 7 connected with the outer lead pipes f ofeach pair, and the heights of all of said stand pipes decreases from thefront of the body I) backwardly as clearly shown in Fig. l and terminateparallel with the position of the perforated cover 6 of the body b andthe torches f have a staggered arrangement as clearly shown in Figs. 1and 2. v

The tanks (1 are provided at the front ends thereof with pressure gagesg which are connected therewith bv pipes 9 and said tanks are alsoprovided at their front and rear ends with vertically arranged air pumpsit within which are placed pistons, not shown, but operated by rods itcomposed of separate parts connected at if, and connected with the rods7& is a rectangular frame lever 2' shown detached in Fig. 5. The lever'5 consists of a frame, rectangular and oblong in form and said frame ismounted in the top of the body I), and the side members 11 thereof passout through the front and rear ends of the body and are provided withyoke-shaped handles 2' by which it may be manipulated and said framelever is supported in central, vertical standards 2' secured to the topsof the tanks (Z as shown at in Fig. 3, and the front and rear ends ofthe body are provided with vertical slots 2' through which the sidemembers of the frame lever 2' pass, and by means of this constructionthe pumps it may be operated so as to force air into tanks (Z andincrease the pressure therein whenever desired.

In the use of this apparatus the torches f are ignited and the snow isshoveled into the hopper c and falls into the chamber 6 and is melted bythe flames j from the torches, said flames being projected transverselyof the bottom of the chamber 1), and the water from the melted snowflows through the perforated cover I) of the trough and through saidtrough and passes back through the rear end of the body and isdischarged through the parts of and d as will be readily understood, andif in this operation any stones or other foreign substances should bethrown into the body with the snow they may be removed through the door6.

The entire apparatus is simple in construction and effective inoperation and while I have shown and described the preferred formthereof, my invention is not limited to the details of constructionherein shown and described and changes in and modifications of the saidconstruction may be made, within the scope of the appended claims,without departing from my invention or sacrificing its advantages. Thetorches 7' are provided with needle valves and said torches may be ofany preferred construction. and while I have referred only to gasoleneas a fuel, any suitable liquid or gaseous fuelmav be employed.
